- Pachyonychia Congenita 4 Omim
  
  A number sign (#) is used with this entry because pachyonychia congenita-4 (PC4) is caused by heterozygous mutation in the KRT6B gene (148042) on chromosome 12q13. Description Pachyonychia congenita (PC) is an autosomal dominant genodermatosis with the main clinical features of hypertrophic nail dystrophy, painful and highly debilitating plantar keratoderma, oral leukokeratosis, and a variety of epidermal cysts. Although the condition had previously been subdivided clinically into Jadassohn-Lewandowsky PC type 1 and Jackson-Lawler PC type 2, patients with PC were later found to have a mixed constellation of both types, leading to a classification of PC based on genotype (summary by Sybert, 2010; Eliason et al., 2012; McLean et al., 2011). For a discussion of genetic heterogeneity of pachyonychia congenita, see 167200. Historical Classification of Pachyonychia Congenita Gorlin et al. (1976) suggested that 2 distinct syndromes are subsumed under the designation pachyonychia congenita.
- Pachyonychia Congenita Orphanet
  
  Pachyonychia congenita (PC) is a rare genodermatosis predominantly featuring painful palmoplantar keratoderma, thickened nails, cysts and whitish oral mucosa. Epidemiology The prevalence is not known but approximately 1000 patients have been registered to date worldwide. Clinical description PC presents clinically as a spectrum of conditions. PC onset is variable with most cases manifesting soon after birth, others becoming clinically apparent only in late childhood and rarely in adulthood. The first signs of the disease usually are thickened nails or neonatal teeth.
- Pachyonychia Congenita Gard
  
  Pachyonychia congenita (PC) is a rare inherited condition that primarily affects the nails and skin. The fingernails and toenails may be thickened and abnormally shaped . Affected people can also develop painful calluses and blisters on the soles of their feet and less frequently on the palms of their hands ( palmoplantar keratoderma ). Additional features include white patches on the tongue and inside of the mouth (leukokeratosis); bumps around the elbows, knees, and waistline (follicular hyperkeratosis); and cysts of various types including steatocystoma. Features may vary among affected people depending on their specific mutation.

- African Trypanosomiasis Orphanet
  
  Human African Trypanosomiasis (HAT), also called sleeping sickness, is a vector-borne parasitic disease caused by a protozoa of the Trypanosoma genus transmitted by the bite of a tsetse fly (genus Glossina ), that is found under its chronic form (average duration of 3 years) in western and central Africa (in case of the T. brucei gambiense sub-species), and under its acute form (lasting from few weeks to 6 months) in eastern and southern Africa (in case of the T. brucei rhodesiense sub-species). HAT comprises an initial hemo-lymphatic stage characterized by fever, weakness, musculoskeletal pain, anemia, and lymphadenopathy, along with dermatologic, cardiac and endocrine complications or hepatosplenomegaly, followed by a meningo-encephalitic stage characterized by neurologic involvement (sleep disturbances, psychiatric disorders, seizures) that progresses, in the absence of treatment, towards a fatal meningoencephalitis.
Glycogen Storage Disease Type 0 Medlineplus

Glycogen storage disease type 0 (also known as GSD 0) is a condition caused by the body's inability to form a complex sugar called glycogen, which is a major source of stored energy in the body. GSD 0 has two types: in muscle GSD 0, glycogen formation in the muscles is impaired, and in liver GSD 0, glycogen formation in the liver is impaired. The signs and symptoms of muscle GSD 0 typically begin in early childhood. ... Because some people with muscle GSD 0 die from sudden cardiac arrest early in life before a diagnosis is made and many with liver GSD 0 have mild signs and symptoms, it is thought that GSD 0 may be underdiagnosed. Causes Mutations in the GYS1 gene cause muscle GSD 0, and mutations in the GYS2 gene cause liver GSD 0.

  A number sign (#) is used with this entry because of evidence that liver glycogen storage disease-0 (GSD0A) is caused by homozygous or compound heterozygous mutation in the GYS2 gene (138571), which encodes glycogen synthase-2, on chromosome 12p12. ... Mapping Orho et al. (1998) established linkage of glycogen storage disease 0 to intragenic and flanking polymorphic markers of the GYS2 gene on chromosome 12p12.2. Molecular Genetics In affected members of 5 families with liver glycogen storage disease 0, Orho et al.

- Glycogen Storage Disease Due To Hepatic Glycogen Synthase Deficiency Orphanet
  
  A genetically inherited anomaly of glycogen metabolism and a form of glycogen storage disease (GSD) characterized by fasting hypoglycemia. This is not a glycogenosis, strictly speaking, as the enzyme deficiency decreases glycogen reserves. Epidemiology It is an extremely rare disease; about 20 cases have been reported in the literature so far. Clinical description It commonly appears in infancy or in early childhood. Patients present with morning fatigue and fasting hypoglycemia (without hepatomegaly) associated with hyperketonemia but without hyperalaninemia or hyperlactacidemia.
- Glycogen Storage Disease Type 0, Liver Gard
  
  Glycogen storage disease type 0, liver (liver GSD 0), a form of glycogen storage disease (GSD), is a rare abnormality of glycogen metabolism (how the body uses and stores glycogen, the storage form of glucose). Unlike other types of GSD, liver GSD 0 does not involve excessive or abnormal glycogen storage, and causes moderately decreased glycogen stores in the liver. ... This condition differs from another form of GSD 0 which chiefly affects the muscles and heart ( Glycogen storage disease type 0, muscle ) and is thought to be caused by mutations in the GYS1 gene.

Glycogen storage disease type 0 Glycogen storage disease type 0 has defect in glycogen synthase Specialty Medical genetics Glycogen storage disease type 0 is a disease characterized by a deficiency in the glycogen synthase enzyme (GSY). ... Serum electrolytes calculate the anion gap to determine presence of metabolic acidosis ; typically, patients with glycogen-storage disease type 0 (GSD-0) have an anion gap in the reference range and no acidosis. ... In patients with glycogen-storage disease type 0, hyperlipidemia is absent or mild and proportional to the degree of fasting. ... In patients with glycogen-storage disease type 0, urine ketones findings are positive, and urine-reducing substance findings are negative. ... The identification of asymptomatic and oligosymptomatic siblings in several glycogen-storage disease type 0 families has suggested that glycogen-storage disease type 0 is underdiagnosed. [2] Mortality/Morbidity [ edit ] The major morbidity is a risk of fasting hypoglycemia, which can vary in severity and frequency.

- Nevus Comedonicus Omim
  
  A number sign (#) is used with this entry because of evidence that nevus comedonicus (NC) is caused by somatic mutation in the NEK9 gene (609798) on chromosome 14q24. Description Nevus comedonicus (NC) is a rare type of epidermal nevus with predilection for the face and neck area. The condition develops within the first decade of life in most patients. NC is characterized by dilated, plugged follicular ostia containing lamellar keratinaceous material and grouped in a honeycomb pattern; the distribution of lesions may be unilateral, bilateral, linear, interrupted, segmental, or along the lines of Blaschko. NC may be nonpyogenic with an acne-like appearance or associated with the formation of cysts, papules, pustules, and abscesses.

- Pseudopili Annulati Omim
  
  Description Pseudopili annulati is an unusual variant of normal hair characterized by a banded appearance of the hair under reflective light, as observed in pili annulati (180600), but resulting from a distinct underlying physical defect. There is no increased hair fragility (Price et al., 1970). Clinical Features Price et al. (1970) reported a 9-year-old girl with blond hair whose scalp hair showed light and dark banding since infancy. Light microscopy showed that the banding appeared only if the light struck the hair at right angles to the long axis of the hair, which was distinct from that observed with pili annulati. Polarizing light indicated variability in the thickness of the hair shaft, and illuminating light did not show bands, 2 additional features that distinguished it from pili annulati. Further examination of the hair shaft showed that the pseudopili annulati hairs had periodic widening and narrowing, that the fiber cross-section was roughly elliptical, and that a periodic twisting of the hair (30 to 40 degrees in 2 alternating directions) was superimposed on the ellipticity.

- Ringed Hair Omim
  
  Description Pili annulati, or 'ringed hair,' is a disorder in which scalp hairs show alternating light and dark bands. It is often an incidental finding, and the hair usually does not show increased fragility (Green et al., 2004). See also pseudopili annulati (613241), a distinct entity. Clinical Features Cady and Trotter (1920) reported 3 unrelated families with ringed hair. The condition was restricted to hairs on the scalp. Based on refractive patterns under transmitted and reflective light, Cady and Trotter (1920) concluded that the light areas were caused by the presence of gas in the interstices of the medulla and cortex of the hair shaft, and not by lack of pigmentation. Ashley and Jacques (1950) reported a 4-generation pedigree with ringed hair inherited in an autosomal dominant pattern.
- Pili Annulati Gard
  
  Pili annulati is a hair disorder. In pili annulati, affected hair has a pattern of light and dark banding. People with pili annulati may describe their hair as "striped" or as having silvery beads. Pili annulati typically involves 20-80% of scalp hair, however it can involve facial and body hair as well. Affected hairs may be more prone to breakage. Pili annulati can present in infancy, childhood, or later in life. It can be seen with the naked eye, however it may be more difficult to see in people with dark hair.
- Ringed Hair Disease Orphanet
  
  Pili annulati is an isolated, benign hair shaft abnormality, usually presenting after the age of 2 and affecting the hair of the scalp or very rarely beard, axillary, or pubic hair, that is characterized by a banded or speckled appearance due to alternating light bands (corresponding to air-filled cavities within the cortex of the affected hair shafts) and dark bands. The bands have a lifelong duration, may only be detectable under light microscopy, are more apparent in fair-colored hair or with age-related graying, and have no effect on hair growth or fragility in the vast majority of cases.

- Pili Torti Orphanet
  
  Pili torti is a hair shaft abnormality characterized by flat hair that is twisted at irregular intervals. Hair is normal at birth but progressively stops growing long and becomes fragile. Pili torti can be isolated or occur in association with syndromes such as Menkes disease or Bazex syndrome (see these terms).
- Pili Torti, Early-Onset Omim
  
  Description Pili torti, or twisted hair, is a condition in which the hair shafts are flattened and rotated along their long axis. Hairs are fragile and break at short length. Some patients may have associated dental or nail findings, and many have resolution of the fragile hair at puberty (review by Dawber, 1996). Pili torti is also a feature in several disorders, including Bjornstad syndrome (BJS; 262000), Bazex syndrome (BZX; 301845), and Menkes disease (309400). Clinical Features Pili torti was first described and named by Ronchese (1932), who observed 2 affected Italian sisters. The proband had dull blonde scalp hair that was 'lank and frizzy, with a wild, bushy appearance.'
- Pili Torti Gard
  
  Pili torti is a rare hair condition characterized by fragile hair. In pili torti hair has a flattened shaft with clusters of narrow twists at irregular intervals. Some cases may be inherited in autosomal dominant or autosomal recessive patterns, while others are acquired. In the inherited form, symptoms tend to be present from early childhood. It can occur alone or as part of other diseases like ectodermal dysplasias , Menke disease , Bjornstand syndrome , or Bazex syndrome . Acquired cases of pili torti may be associated with anorexia nervosa , malnutrition, oral retinoid treatment, or inflammatory scalp conditions (e.g., cutaneous lupus erythematousus ).
